Offensive Ability <Armageddon> If Nova has a Dodgeball she can deploy a tactical mark somewhere and call a nuke in like 2 or 3 seconds delay (nuke=dodgeball) better ball = more radius and damage. She is stunned while she calls down the nuke.(Upgrades decrase the cooldown)

Defensive Ability <Scoped (Passive)> The last Unit that Nova shoot with a dodgeball gets scoped for several seconds and takes bonusdamage (like 10% and with upgrades up to 30%?).

Second Unit:

Queen Stats:Health 4Power 3Speed 1

Offensive Ability <Zerg Rush!> In 3 Sec delay and overlord will bring 3 Banelings. The Banelings are going to attack the nearest enemie. (They are faster on the creep and last for like 5sec or something can get shoot down) Upgrades increase the amount of banelings up to 5 or something.

Defensive Ability <Creep Tumor> Queen places a Tumor that spreads out creep in a small Area that increases Speed by Allies and herself. (Needs 10sec to build and has health upgrades like the SCV rocket tower)

Thanks for the suggestions! One thing I have to mention is that Hero Units from the campaign (Raynor, Zeratul, Nova, etc.) do not have team colors on them, so I won't be able to put them in this game (it'd be impossible to tell which are on your team and which are on the other). That being said, I think these abilities would fit the spectre, who I believe does have team colors.

I definitely want to make a Queen in the future so thank you for your ideas! Right now I'm working on the High Templar, Archon, Hellion, and Hydralisk, but I love new ideas and will keep these ones in mind. I actually have received several requests for a Queen and a couple people have suggested a creep tumor ability, so I'm sure you'll be seeing it in the future!
